Bnei Brak (or Bene Beraq) (Hebrew: בְּנֵי בְרַק‎‎  (audio) (help·info), Bəne βəraq) is a city located on Israel's central Mediterranean coastal plain, just east of Tel Aviv, in the Dan metropolitan region and Tel Aviv District. Bnei Brak is a center of Orthodox Judaism.

Bnei Brak covers an area of 709 hectares. According to figures of the Israel Central Bureau of Statistics, at the end of 2009, the population was 154,400, with an annual growth rate of 1.7%. Bnei Brak is one of the poorest and most densely populated cities in Israel.

Bnei Brak takes its name from the ancient Biblical city of Beneberak, preserved in the name of the Palestinian village of Ibn Ibraq ("Son of Ibraq/Barak") which was located 4 kilometers (2.5 mi) to the south of where Bnei Barak was founded in 1924.

Bnei Brak was founded as an agricultural village by Yitzchok Gerstenkorn and a group of Polish chasidim. Due to a lack of land many of the founders turned to other occupations and the village began to develop an urban character. Arye Mordechai Rabinowicz, formerly rabbi of Kurów in Poland, was the first rabbi. He was succeeded by Rabbi Yosef Kalisz, a scion of the Vurker dynasty. The town was set up as a religious settlement from the outset, as is evident from this description of the pioneers: "Their souls were revived by the fact that they merited what their predecessors had not. What particularly revived their weary souls in the mornings and toward evening, when they would gather in the beis medrash situated in a special shack which was built immediately upon the arrival of the very first settlers, for tefilla betzibbur (communal prayer) three times a day, for the Daf Yomi shiur, and a Gemara shiur and an additional one in Mishnayos and the Shulchan Oruch."bnei brak was once mentioned in a mishnah
